Detailed explanation-1: -Air is inhaled through the mouth or the nose. The sequence of air passage during inhalation is as follows: Nostrils→pharynx→larynx→trachea→alveoli.
Detailed explanation-2: -Air is inhaled through the nostrils and warmed as it moves further into the nasal cavities. Scroll-shaped bones, the nasal conchae, protrude and form spaces through which the air passes. The conchae swirl the air around to allow the air time to humidify, warm, and be cleaned before it enters the lungs.
Detailed explanation-3: -Air enters the respiratory system through the nose. As the air passes through the nasal cav ity, mucus and hairs trap any particles in the air. The air is also warmed and moistened so it won’t harm delicate tissues of the lungs.
